High entropy materials promised a lot of opportunities in the field of structural metal alloys due to their extraordinary mechanical properties. It is also rising up in many other fields including structural ceramics, thermoelectricity, piezoelectricity, etc. However, thorough studies of designing high entropy materials for energy storage and conversion are largely absent. The major obstacle in this field is whether the mixing of multi-component species will necessarily improve targeted properties such as ion transport and chemical absorption/adsorption. In this talk, it will be demonstrated that high entropy can benefit the design of battery cathode materials with high energy density and high rate performance, as well as solid-state ionic conductors that deliver ultra-fast ion conduction. Moreover, future opportunities for designing other high entropy energy materials will also be demonstrated.
